THE DISTRIBUTION AND PROPAGATION OF ENDOPHYTIC BACTERIA WITHIN THE CELLS OF LILY TISSUE

Distribution of endophytic bacteria was observed within the tissue and cells of bulb, roots, stem, leaves and floral bud of lily, but the number of bacteria is different. The number of bacteria is highest within the bulb cells of lily. It my-be relating to the content of nutriment. The number of the bacteria within the cells of outside scale is higher than that inside. In the bulb of lily the bacteria within the meristematic cells of growing tip are less or without, but there are more in the mature cells of base. Within the epidermis cells of outside scale, numerous tube-lick structures which appear to arbuscules as infection line is shown in the most outside layer of lily bulb. These structures associated with cell wall, it is possible for an infection passage of the bacteria from soil. In our inference, the bacteria within the cells is no endophyte, because the propagation of the bacteria can distribute from mature cells containing bacteria into the meristematic cells following the development. The propagational way of the bacteria passed through is a pore of plasmodesma between pit-pair on the wall. After the microtubele of the plasmodesma is damaged, the bacteria goes from one cell into another cell following cytoplasm.
